Application Information

The surfaces to be coated should be clean, sound, and free from contamination. Remove any traces of curing compound, laitance, organic growth   or any other loose materials. This is best obtained by using high pressure water or light grit blasting. Substrate containing honey combing, damaged or deteriorated concrete should be repaired using suitable repair mortars from DCP repair systems before coating.

No special primer is required, but substrate should be pre-soaked with clean water prior to application of AquaProof 2K.

To ensure proper mixing, a mechanically powered mixer or drill  fitted with suitable paddle should be used. Add the liquid component of AquaProof 2K to a clean container.   

The powder component is then added slowly to the liquid while mixing continuously with low speed mixer/drill (400 - 600 rpm). Mixing time should be continued for 3 minutes until a uniform consistency is obtained.

AquaProof 2K can be applied by brush, or spray machines. The mixed material should be brushed well into the surface. Strike off with brush in one direction. Care must be taken not to spread the materials too thin.
When the material begins to drag, do not add any water, but dampen the surface again.
Leave the first coat overnight to cure before applying the second coat. If the first coat is left for more than one day or if it is very dry, pre-soaking with clean water is needed before applying the second coat.
The second coat shall be applied by brush in a similar way to the first layer but preferably perpendicular to the previous layer to ensure good bond and coverage.
